A damper device according to one embodiment, for example, includes: a rotating member that is rotatable about a rotational axis, the rotating member including a base portion that is plate-like and support portions that is attached to the base portion and extends in an axial direction of the rotational center; and a plurality of weight members disposed partially overlapping each other in the axial direction, the weight members being provided with tracks in respective overlapped parts of the weight members, the tracks guiding the support portion to be swingable with respect to the rotating member, wherein the support portion is shared in the tracks provided in the weight members.

Damper device

A damper includes a first, second, and third rotation member rotatable around a rotation axis, a first elastic portion interposed between the first rotation member and the second rotation member and elastically deformed by a relative rotation between the first rotation member and the second rotation member, a second elastic portion interposed between the second rotation member and the third rotation member and elastically deformed by a relative rotation between the second rotation member and the third rotation member, and a dynamic vibration absorber. The dynamic vibration absorber includes a rolling element that is positioned at an inner side relative to the first elastic portion and the second elastic portion in a radial direction of the rotation axis, and is rotatable relative to the second rotation member.

Damper

A damper apparatus includes a first rotation member, a second rotation member, a first elastic portion interposed between the first and the second rotation members and elastically deformed by a relative rotation between the first and the second rotation members, a third rotation member, a second elastic portion interposed between the second and third rotation members and elastically deformed by a relative rotation between the second and third rotation members, and a dynamic vibration absorber. The dynamic vibration absorber includes an anchor member and a third elastic portion that is interposed between the anchor member and the second rotation member and that is elastically deformed by a relative rotation between the anchor member and the second rotation member. At least the third elastic portion is positioned at an inner side of the first elastic portion and the second elastic portion in a radial direction of the rotation axis.
